DEVZCE FOR .dPPLYING GREASE TO ROLLS.

To all whom it may concern:

1 v l v I)? it knou n that l. 1 union (.iUWA-N. citizen oithe ,nited States, resid-.

ing at Newport. in the. county of Cainphell and State of Kentucky, have invented certain new and useful Improvements in Deviees for Applying Grease to Rdlfisgot which the following is a specification.

This invention relates to luhricators and more particularly to means for applying grease in a fluid state to rolls employed in iron and steel rolling mills and similar" niachiiier v.

The object tit-the invention isto provide a luln-icator in which grease or other lulu-L cant-is ted fluid pressure to the rolls, means heing provided for heating thegrease prior to its delivery to the rolls.

to the rolls, and means for heating the grease during its passage through the supply pipe.

A still further object of the invention is generally to improve this class ot devices so as to increase their utility, durability and e'ltl 'iency.

Further objects and advantages will appear in the. following description, it being understood that various changes in form,

v proportions and minor details of construction may he resortedto within the scope of the appended claims.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result reference is to he had to the following description and accompanying drawin s, in which:

Figure 1 is a side elevation partly in section of a luhricator constructed in accordance with my invention; Fig. 2 is a longitudinal sectional view on an enlarged scale showing the construction of the supply pipe and fluid nozzle.

Corresponding and like parts are referred to the following description and indi- Specification of Letters Patent.

cated in all the views of the drawings by the same reference characters.

The device comprises a. tank or receptacle or" any desired shape or cross sectional formation, said tank being provided with a cover G and adapted to contain a quantity of grease or other lubricant, indicated at 7. Disposed beneath the tank 5 and-supporting the latter is a the box 8 for the purpose of heating the grease in the tank 5 so as to reduce it to a fluid state prior to its delivcry to the rolls.

Extending laterally from one side of the tank 5 and communicating with the interior thereof, is a supply pipe 9 having an angular extension 10, the end of which is closed at 11, there being a series of perforations 12 formed in one side of the extension 10 and through which the grease is fed to the necks of the rolls. Disposed Within the supply ipe 9 is a nozzle 13 to which is connected fluid supply pipe,'14c. The rear end of the .nozzle 13 is c losctl and-extends to a point adjacent the taplnib, While the front end of the nozzle isopcn and terminates near the bond 15. The nozzle 13 isdisposed concen- ,tric vvithand spaced from the interior Walls of the supply pipe 9 sh as to form circumferential chamber 16 to permit the passage of grease from the tank 5 to the perforations 12. By making the nozzle 13 approximately the same length as the pipe 9, the

14 will tend to heat the grease and thus prevent the same from congealing during its passage through said pipe. to the perforations therein.

Connected in the fluid supply pipe 1 a valve 17 for regulating the quantity of liuid delivered to the nozzle '13, there being a similar valve 18 connected in the supply pipe 9 he-tiveen the tank 5 and the fluid pipe tity of grease discharged through the perforations in said supply pipe.

In operation, the grease in the tank 5 is first heated, after which the valve 18 is moved to open orpartially open position and the valve 17 adjusted so as to admit steam, air'or other fluid under pressure to the interior of the supply pipe 9.

"the tiuiddischarged at the active end or" 3 the nozzle will positively terse the grease steam entering said nozzle through the pipe H for the purpose of regulating the quan through the perforations in the supply pipe to the rolls and also tend to create a suction inthe supply pipe 9 and thus feed the grease through the supply pipe to said perforations, as will be readily understood.

\Vhile the lubricating mechanism principally designed for supplying lubricant to rolls, it will of course be understood that the device ma be used with equally good results for other purposes without departing front the spirit of the invention.

Having thus described the invention, what is claimed as new is:

1. A device of the class described inclnding a tank adapted to contain a lubricant. means for heating the exterior of the tank, a supply pipe having one end. thereof co|n- Inunicating with the interior of the tank and its other end perforated, and a fluid pres sure heating device centered within the supply pipe and terminating short of the perforated end thereof, said fluid pressure device also serving to discharge the lubricant through the perforations in the supply pipe.

2. A device of the class described including a tank adapted to contain a lubricant, a supply pipe having one end thereof cominunicating with the interior of the tank and' its other end perforated, means for heating the exterior of the tank to liquefy the lubricant contained therein, and fluid pressure means independent of said tank for heating the lubricant during its passage through the supply pipe to the perforations, s id fluid pressure means also serving to distcharge the lubricant through the perforations-in said supply pipe.

3. A device of the class described including a tank adapted to contain a lubricant, a supply pipe having one end thereof contmunicating with the interior of the tank and its other end perforated, means for heating the exterior of the tank, fluid pressure means independent of the tank and tank heating means for heating the lubricant during its passage through the supply 1 pipe from the tank to the perfm'ations in said supply pipe, and means for controlling the flow of lubricant through the suppl pipe.

-t. device of the class described including a tank adapted to contain a luln'icant, a supply pipe having one end thereof comninnicating with the interior o'fthe tank and its other end perforated. means/for heating the exterior of the tank, a nozzle int'lependcnt of the tank disposed within and spaced from the walls of the supply pipe to form a cir lnnl'erentia'l chamber terminating short of the perforations in said supply pipe. and a source of fluid pressure independent of the tank connnunicating with the nozzle 'for.he; .ling the lubricant during its passage through the chamber. said fluid pressure means also serving to discharge the lubricant through the perform tious in the lll)l l pipe.-

' 3. device of the class described including a tank adapted to contain a lubricant, means for heating the exterior of the tank. a supplv pipe having one end thereof coin- .muntfeating .ivith ihp,ii1.lt%rioi' of the tank and its other end closed, there being perforations formed in the t'valls of the supply pipe at the closed end thereof, a nozzle independent of the tanl disposed within and spaced from" the interior wall of the supply pipe to form a cirotnnfercntial chamber terminating short of the perforations in said supply pipe, a pipe communicating with the.

nozzle for admitting fluid under pressure to saidnozzle to heat the lubri amt. within the chamber, and a valve for controlling the passage of lubricant through the supply pipe.

in testimony whereof I allix my signature in presence of two witnesses.
